Star Wars is hardly the first time adults have enjoyed a pastime that isn't a "deeper pursuit" or sufficiently thought provoking. Heck, "America's pastime" is a game of people hitting a ball with a stick, and has drawn millions of viewers.

If you had a time machine and went back a couple thousand years, I think you'd find that people already did unproductive things for entertainment.

And people have probably been disapproving of younger generations enjoying the wrong entertainment for about as long as we've done things for entertainment.
